functions
The PHP 601 is a high accuracy, dual
input thermometer suitable for use with
RTDs (e.g.: Pt 100) and thermocouples.
The PHP 601 is capable of storing sensor
characteristics and coefficients and can
scan up to 12 sensors using the model
SHP 101 Scanner.
Its main applications include the calibra-
tion of temperature sensors. By using our
CAL'EXPERT software to drive the
PHP 601 thermometer, scanner and a ther-
mal device such as temperature bath, dry
block calibrator or oven, a complete cali-
bration procedure can be performed,
reports generated and certificates printed
for individual sensors.
